Device Prototypes

Pure Paani is exploring an array of distinct pump filter prototypes in order to determine which systems work best in low-income communities. Such devices need to be effective and portable while also being durable and affordable.

The two most feasible filter types include hollow-fiber, ultra filtration membranes commonly used in gravity and RO systems and cylinder block filters used in under-sink systems. Pure Paani is also considering building its own filter media out of stock materials. With these technologies in mind, Pure Paani has developed the following model set.
